Ah awesome! Thanks for the quick reply.

I should have been more clear, this is streaming off a synology nas via dlna or smb.

We'll still be good with that setup?

How badly will it affect the battery playing high bitrate mkvs do you think?

Can't wait for the jailbreak!

It just doesn't make sense to guess around here. Learn some patience and you will see it once the bread is out of the furnace.

See iOS FAQ (wiki). It should be pretty okay with h.264 videos, but anything else will be CPU/software decoded, which will take up much more battery life.
